/**
 * enum ieee80211_rate_flags - rate flags
 *
 * Hardware/specification flags for rates. These are structured
 * in a way that allows using the same bitrate structure for
 * different bands/PHY modes.
 *
 * @IEEE80211_RATE_SHORT_PREAMBLE: Hardware can send with short
 *	preamble on this bitrate; only relevant in 2.4GHz band and
 *	with CCK rates.
 * @IEEE80211_RATE_MANDATORY_A: This bitrate is a mandatory rate
 *	when used with 802.11a (on the 5 GHz band); filled by the
 *	core code when registering the wiphy.
 * @IEEE80211_RATE_MANDATORY_B: This bitrate is a mandatory rate
 *	when used with 802.11b (on the 2.4 GHz band); filled by the
 *	core code when registering the wiphy.
 * @IEEE80211_RATE_MANDATORY_G: This bitrate is a mandatory rate
 *	when used with 802.11g (on the 2.4 GHz band); filled by the
 *	core code when registering the wiphy.
 * @IEEE80211_RATE_ERP_G: This is an ERP rate in 802.11g mode.
 * @IEEE80211_RATE_SUPPORTS_5MHZ: Rate can be used in 5 MHz mode
 * @IEEE80211_RATE_SUPPORTS_10MHZ: Rate can be used in 10 MHz mode
